Diseño y construcción de una máquina peletizadora automatizada destinada para la producción de pellets (balanceado) para animales porcinos

Abstract

This work aimed to design and construct an automated pelletizing machine using a SCADA system (Supervision, control, and data acquisition) to produce pellets (balanced) for porcine animals. The QFD (Quality Function Deployment) methodology was used to choose the best design alternative, specifically the quality house. In the application of the method, the mechanical elements of the machine were designed. In addition to the automation of the engine, the various electronic elements were selected for the proper programming of the embedded system and the subsequent creation of the graphical user interface. Using the graphical user interface resulted in the visualization of 3 variables: temperature, humidity, and level, where it was possible to monitor the variation suffered by these variables during the operation of the machine. It is concluded that the humidity variable within the pelleting process directly affects the final product since if it is in a percentage of humidity higher than 20%, low-quality pellets are produced. In addition, the use of the graphical interface provides essential information focused on monitoring the three variables mentioned, allowing the creation of records for production analysis and maintenance plans. It is recommended to consider the operating time of both the mechanical and the electronic parts to avoid any significant impact that reduces the machine's useful life.
